OPERATION MANUAL

Introduction
I
Introduction
The Ethernet I/F option is an interface to carry out communications with F381A/F388A(s) through an
Ethernet.
Supported functions are set value read/write, waveform read/write, hold result read, wave No. read/write,
etc.
WARNING
The F381A/F388A(s) is factory-set as follows:
・IP address (192.168.0.1)
・Subnet mask (255.255.255.0)
・Default gateway (unused)
If there is a need to change the settings of the IP address, subnet mask, and default
gateway, be sure to change the settings and then carry out wiring of Ethernet cable(s).

②When the F381A/F388As and client exist in the same network.
③When the F381A/F388As and client exist in different LANs.
Connect with the client through a hub, etc., by using straight cables.
3. Check that the LINK lamp is lit.
If the lamp is not lit, it is considered that the equipment (hub, host, etc.) connected with the
F381A/F388A(s) is not running normally, or the cable(s) is wired incorrectly or broken.
Check that the equipment (hub, host, etc.) connected with the F381A/F388A(s) is running
normally, and the cable(s) is wired correctly and is not broken.
4. Check the connection of the client and each F381A/F388A.
i) With the power of the F381A/F388A OFF, execute a PING command (see "・What is
PING?" on P.12.) from the client to the IP address of the turned-OFF F381A/F388A,
and check that no response is made. If a response is made, the specified IP address is in
use. Check that the IP address is not used in other equipment.
ii) Turn on the power of the F381A/F388A, and execute a PING command from the client
to the IP address of the turned-ON F381A/F388A, and check that a response is made.
If no response is made, connection between the client and F381A/F388A is not
established.
Check that the route between the equipment from which the PING command was sent
and F381A/F388A is established and that the network settings of the client and F381A/

* Check with your network administrator for the use environment.
5. Check the establishment of connection.
Start the client software, and connect with the F381A/F388A.
Upon establishment of connection, the IP address of the connection-established equipment
is displayed under "Connect IP" on the Ethernet setting item screen of the F381A/F388A.
(If the F381A/F388A is connected with the client through a router, the address of the router
close to the F381A/F388A is displayed.)
If connection is not established, the settings of the client software may be wrong. Check the
specifications of the IP address, port number (50381 (TCP/IP), etc., for errors.
* Check with your network administrator for the use environment.

Explanation for setting
Equipment ID: Set the equipment ID.
When connecting two or more F381A/F388As to Ethernet, set each equipment ID
to identify them.
* This is the same as the equipment ID of the SD card slot option.
IP/Mask: Set the IP address and subnet mask.
- IP address
①: 1 to 223 (127 cannot be set.)
②: 0 to 255
③: 0 to 255
④: 0 to 255
* 0.0.0.0 cannot be set.
- Subnet mask
The subnet mask setting range varies according to the setting of the IP address.
When IP address ①is in the range of 1 - 126:
①:255
②: 0, 128, 192, 224, 240, 248, 252, 254, 255
③: When ②is 255: 0, 128, 192, 224, 240, 248, 252, 254, 255
When ②is other than 255: 0
④: When ③is 255: 0, 128, 192, 224, 240, 248, 252

- About the combination of the IP address and subnet mask
Unsettable combination:
When the IP address and subnet mask are expressed in binary, IP addresses in which
all the bits 0-specified to the subnet mask become 0 or 1 cannot be set.
Example) Unsettable combination
Gateway: Set the default gateway.
- Default gateway
①: 0 to 223 (127 cannot be set.)
②: 0 to 255
③: 0 to 255
④: 0 to 255
* If 0.0.0.0 is set, the default gateway is unused.
In such a case, "---.---.---.---" is displayed.
* If "0" is set to ①, values other than 0 cannot be set to ②, ③, and ④.
- Conditions under which the default gateway cannot be set
When the IP address, subnet mask, and default gateway are expressed in binary, if the
bits 1-specified to the subnet mask do not correspond to the IP address, the specified
default gateway address cannot be set.
Also, default gateway addresses in which all the bits 0-specified to the subnet mask
become 0 or 1 cannot be set.

Point
At power-on, it takes about 15 seconds for the communications of the Ethernet I/
F option to become ready. During that time, connection and changes of the
settings of the Ethernet I/F option cannot be made.

6. Network
・What is a LAN?
For carrying out communications with multiple pieces of equipment, a group of a certain size is
normally formed for managing and geographical reasons.
This group is called a LAN (Local Area Network).
・How to form a LAN
The same network address needs to be set in one LAN.
When the IP address is expressed in binary, the IP address of the part 1-specified to the subnet mask
is the network address.

・How to connect different LANs
For connecting different LANs, a router needs to be connected between them, and the address of the
router should be set to the default gateway.
・What is a connection?
Virtual circuit(s) provided between the pieces of equipment to carry out communications is called
connection.
・What is the establishment of a connection?
A state in which communications can be carried out between the pieces of communicating
equipment by providing virtual circuit(s) for communications is called the establishment of a
connection.
Taking a telephone as an example, it refers to: picking up the telephone receiver, inputting the
telephone number of the other end, and the other end answering the telephone.
The F381A/F388A does not send a reply to commands (set value read/write, waveform read/write,
etc.) until connection with the F381A/F388A is established.
・What is a host?
The equipment that is capable of transmission and reception in communication by using a protocol
is called a host.
・What is a client?
The host that tries connecting to establish a connection is called a client.
・What is a server?
The host waiting for a connection in establishing a connection is called a server.
The F381A/F388A is a server, and after power-on, it is brought to a state in which it waits for

7.Cautions in creating client software
12
・What is PING?
It is a client side program to diagnose the network status.
You can check the communication status according to the replay made by sending packet data that
requests a replay to the equipment the network status of which you want to check.
* For the method of operation, check with your network administrator for the use environment.
・What is "keep-alive"?
Communications are carried out periodically to check that the connection is valid.
Under circumstances where communications are not carried out for a long time, it is not clear
whether communications are not carried out intentionally or communications cannot be carried out
due to some problem.
Therefore, even under such circumstances where communications are not carried out for a long
time, whether or not the connection is valid is checked by sending a packet informing that the
connection is continuing to the other end and checking the arrival of the packet at the other end.
If the connection is invalid, it is cut off by a predetermined number of times.
7. Cautions in creating client software
- Protocol TCP/IP
- Port number Set 50381 to the port number.
- Keep alive The F381A/F388A sends a packet at intervals of 30 seconds, and checks three
times.
-Checking of communications carried out with an intended F381A/F388A
For use of two or more F381A/F388As, set the equipment ID avoiding
overlap to identify them.
After power-on and the establishment of a connection with the F381A/F388A,
read the equipment ID and check the consistency between the IP address and
equipment ID.
